Outcomes
Primary outcome [1] 843 0
Evaluation of the determinants of immune recovery (namely CD4+ T lymphocyte and HIV viral load). These factors include age, sex, cigarette smoking, Hepatitis C co-infection, CD8+ T-lymphocyte count, nadir and baseline CD4+ T-lymphocyte, baseline HIV viral load, time to undetectable HIV viral load and composition of HAART.

Eligibility
Key inclusion criteria
First antiretroviral regimen composed of HAART as defined by at least three antiretrovirals. Controlled viremia for a period of at least 12 months following commencement of HAART. Controlled viremia is defined as HIV viral load of 500 copies/mL on bDNA testing (versions 2 and 3) and <400 copies/ml measured by RT-PCR assay by 6 months treatment. CD4 cell count <500 at commencement of HAART. Measurement of CD4+ cell count on at least 3 time points, in the 12 months post commencement of HAART.
Minimum age
18 Years

Can healthy volunteers participate?
No
Key exclusion criteria
Exclude patients treated for HIV seroconversion illness. Exclude patients on immunomodulatory therapy such as IL-2, hydroxyurea or prednisolone or who have received an HIV therapeutic vaccine.
